Health, Safety and Environment has its own terms, acronyms and abbreviations.

In some cases the terms occur in everyday speech but, in Health and Safety, some have different shades of meaning to their common usage.

We have attempted to express our definitions in laymen's terms and therefore should not be assumed to have any legal standing.
